There are growing numbers of African international students studying at Higher Education Institutions (HEIs) in North America and the United Kingdom. Intercultural mentoring is one response to supporting students in navigating the complex cultural, social, and academic transitions from home to host countries. This article examines the experiences of 18 participants who had recently mentored African international students attending higher education institutions in Canada or in the UK. Semi-structured interviews with participating mentors were transcribed and analysed from a critical intercultural perspective. Results highlight four themes that provide insight into mentors' approaches to intercultural mentoring: navigating fields of action and intervention, engaging in reflective practice, intercultural mentoring as a relational practice, and mentoring as a decolonising practice. Study findings provide insight into how intercultural mentoring relationships develop and evolve and how mentors approach mentoring relationships as sites that hold transformative learning potential for both mentors and students.
